Hello, for those like me who use a digital mixer as a secondary sound card from Behringer and model X32 Compact and MS Windows,
I have written a free diagnostic software (with the help of two gurus of the sector, Patrick Maillot and Paul Vannatto) in case of malfunctions.
The software talks to the mixer via OSC so just connect the mixer via LAN to the network HUB and indicate the IP of the mixer.
You can download the software at this address: (executable validated by VirusTotal.com)
